Something I did notice is that live streaming using any browser does not work if camera is set to H.265. If I switch the camera back to H.264 live stream works fine. My IPC-HDW5231R-ZE and IPC-HFW4231EP-SE are also set to H.265 and live view in camera web interface works fine for those models. Both of those are 2MP cameras. As a test, I lowered the resolution and bitrate of the 1831E to 4MP, 4Mb/s, and H.265 live stream returned. I would guess that the additional CPU required to run H.265 that 8MP, 6Mb/s, is pushing the CPU limit of this camera. (?)
